Doon- BELL.

SPECIFICATON forming part of Letters Patent No. 682,293, dated September 5, 1899.

Application filed March 14, 1399.

Beit known that 1, HENRY G.VoIGHT, a citia zen of the United States, residing in New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Door-Bells, of which the following is a specification.

My invention relates to improvements in door-bells; and the main objects of my improvement are simplicity and economy in construction and efficiency in operation.

In the accompanying drawings, Figure 1 is a sectional view of my bell, partly in 'elevation, on the line x, Fig. 2. Fig. 2 is afront or plan view of the same with the gong removed; and Fig. 3 is an elevation ofthe saine with a part broken away and one of the movement-plates sectioned on the line y y of Fig. 2, the gong being removed.

Al designates the ring-like base, having lugs 4, to which the movement-plates 5, 6, and 7 Y are secured. Such a base for securing the frame of the movement in bells is of an ordi` nary construction; but a frame composed mainly of one base-plate 5 and two angular plates 6 7 is supposed to be new. i One wing of each of the plates 6 7 is parallel to the plate 5, and the right-angular wings 8 9, respectively, of the. plates 6 7 are at right angles thereto and are held together with a proper space between by ordinary posts 10. angular right wing 9 of the plate 7 has a bridge 11 at its middle portion that spans the space between the wings 8 9 and has secured thereto the post 12, by which the gong B is held in place, whereby the movement-plates also serve the additional function of a post or standard upon which to mount the said gong.

In between the wings 8 9 I mount on a suitable shaft the gear-wheel 13 and pinion 14, and also a lever 15, having a rack 16 at one end for engaging the pinion 14. The said lever is pivoted at 17 and provided with a lug 1S, Fig.v 1, against which the spring 19 bears to normally hold said VVlever in the position shown. A push-rod V32 is pivoted by one end to the lever.15 by means of the pin 20, which pin also projects into a slot 21, Fig. 3, in the wing S of the plate 6 to limit the longitudinal movement of the said push-rod. The other end of said rod is guided in a hole in the plate lthan the striking-head.

5, said end being provided with a longitudinal hole or socket (not shown) in which to insert the push-wire 22 of the push-button 23 in the ordinary manner of connecting similar push-rods with a push wire and button. The position of the slot in the wing 8 of the plate 6 is indicated by broken lines in Fig. l. Between the plate 5 and the parallel wing of the plate 7 there is a gear-wheel 24, that engages with and is driven by the gear-wheel 13 at right angles thereto. Said wheel 24 engages with and drives a pinion 25 on the shaft 26, and on said shaft outside of said plates is the revolving hammer-carrier 27 for the sliding hammers 28. These two hammers may be readily cut from sheet metal and held within the carrier so as to have a limited degree of longitudinal movement therein, as the said two ham mers lie flatwiseone uponV the other. Said hammers are each provided with a striking-head 29 at one end and a shouldered stop 30 at the other end, the said stop being of less weight and of less length from its shoulders Inasmuch as the hammer-carrier is eccentric to the gong it is not necessary to have a lug on the inside of the gong for the hammers to strike. The curved broken line 31, Fig. 2, indicates the position of the inner face of the gong, against which the hammers strike.

By pushing on the push-button 23 the swinging lever 15 is moved against the face of the spring 19, thereby moving the rack 16 and driving the pinion 14 and connected train to drive the hammer-carrier several revolutions in one direction. The centrifugal force will hold the hammers with their striking-heads extended, as shown, until they strike the gong and are pushed back sufliciently to clear the same, after which they will regain their for- The hamgive two'strokes for every revolution of the carrier, and each onerecovers itself ready for the succeeding blows independently of the Upon releasing the push-button the spring 19 drives the train in the reverse direction and gives another series of strokes to the gong. i By my improvement the bell can be cheapl made, and it is very efficient. Only a short IOD stroke of the push-button gives a number of revolutions to the hammer-carrier. By the employment of two flat sliding hammers they may be cheaply constructed of sheet metal and placed latwise one over the other in the same guides, and each hammer slides independently of the other.

It is apparent that some changes from the specific construction herein disclosed may be made, and therefore I do not Wish to be understood as limiting myself to the precise form of construction shown and described, but desire the liberty to make such changes in Working my invention as may fairly come Within the spirit and scope of the same.

I claim as my inventionl. A bell-movement, the frame of which consists mainly of a base-plate and two angular plates, two Win gs of the said angularplates being parallel to the said base-plate and properly spaced therefrom, the other two Wings of the said angular plates extending parallel to each other at right angles to the said other wings and base-plate, substantially as described.

2. In a bell-movement, the combination of the movement-frame with the lever-rack, spring, pinion, Wheel and push-rod, mounted in a plane at right angles to the base of said frame, and the connecting-gearing and hammer-carrier mounted in a plane parallel to the said base, substantially as described.

The combination of a frame with the pivoted lever having the rack, the push-rod connected with the middle portion of said lever and extending longitudinally in a line parallel to the plane of the said rack, a spring acting in opposition to said push-rod, the pinion and gear-Wheel engaging with and driven by the said rack, and bell-striking mechanism driven by the said gear-Wheel, substantially as described.

4. The combination of the revolving ham'- mer-carrier with the two Hat slidin g hammers HENRY G. VOIGII'I.
